S.Vinothkumar · #21 (**permalink**) 09-05-2007, 12:19 AM

Here is a sample code for that Ramesh....

Go thru this...

Code:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.Method = "PUT";
            request.ContentType = ContentType // Here is ur ContentType
            request.ContentLength = byteArr.Length;
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArr, 0, byteArr.Length);
            dataStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Hi there,

I need a PHP web service for C#. IS there any possible for that?

How can I create a PHP Web Service for C#?

can anybody clear me?

S.Vinothkumar · #23 (**permalink**) 09-05-2007, 12:50 AM

Yes....

You can create php web service for C#. Here is sample code...

Code:

//ws.php

require_once("lib/nusoap.php"); 
$ns="http://your.server.address/"; 

$param = array('x' => 'xsd:string','y' => 'xsd:string'); 
$return = array('return'=>'xsd:string'); 

$server = new soap_server(); 
$server->configureWSDL('WS Test',$ns); 
$server->wsdl->schemaTargetNamespace=$ns; 
$server->register('TestFunction',$param,$return,$ns); 

function TestFunction($x,$y){ 

$ret=$x+$y; 

return new soapval('return','xsd:string',$ret); 
} 

$server->service($HTTP_RAW_POST_DATA);

Hi Vinoth,

Thanks for ur kind reply...

It's working for me...but...

Can u clear me the contenttype?

I need to upload image files with the format of Jpg....

thnx in advance!

S.Vinothkumar · #25 (**permalink**) 09-05-2007, 01:18 AM

Ya sure Ramesh!

The ContentType property sets the HTTP content type for the request and response object.

ContentType for Text is

Code:

ContentType = "text/plain"

ContentType for XML is

Code:

Contenttype="text/xml"

ContentType for HTML is

Code:

Contenttype="text/html"

ContentType for icon is

Code:

application/x-mmc.icon;

ContentType for BMP is

Code:

img/bmp

ContentType for RingTone is

Code:

application/x-mmc.ringtone

ContentType for Audio is

Code:

audio/wav

ContentType for JPEG is

Code:

ContentType="image/JPEG"

ContentType for TIFF is

Code:

ContentType ="image/tiff"

and so on...

I am trying to make a client in C# that use a PHP Web Service.

I am using NuSOAP for creating the Web Services. It creates the WDSL ok and C# recognizes it but during run Time its throws an exception.

Has anybody tryied to interoperate with PHP web services and C# client ?

Please let me know your experience.

S.Vinothkumar · #28 (**permalink**) 09-05-2007, 06:40 AM

while it has PHP in it, C# is the one throwing an exception so it's a C# problem.

Check it out in C# programme....

Getting the Webservice running on the .NET server is easy. The hard part was getting the PHP page to call the webservice and return the values that we needed.

Here is a demo method:

Code:

[WebMethod] public Order GetOrder() { Order myOrder = new Order(); myOrder.SalesNum = “123″; myOrder.OrderDate = “05/24/2006″; myOrder.ShipDate = “Tomorrow”; myOrder.PaymentRec = “05/24/2006″; myOrder.OrderStatus = “InProgress”; return myOrder; }

Learn with my posts.....

S.Vinothkumar · #30 (**permalink**) 09-05-2007, 06:59 AM

$result is the return var from the webservice $result[’GetOrderResult’][’SalesNum’] $result[’GetOrderResult’][’OrderDate’] etc…

Hi all,

How can I return IList from a WebService?

I hv tried a lot of time. I can't return IList but I can return arraylist.

Is any sample code for that? Could u pls let me know....

mobilegeek · #32 (**permalink**) 09-06-2007, 01:16 AM

I've noticed that XmlSerializer won't serialize objects that implement IDictionary by default.

you can visit this msdn link for reference.

http://msdn.microsoft.com/msdnmag/is...s/default.aspx

It might be useful for you. Read the last question and answer in the link.

S.Vinothkumar · #33 (**permalink**) 09-06-2007, 01:19 AM

WebMethod framework uses the XmlSerializer plumbing, it's now possible to return DictionarySerializer objects from WebMethods.

For example, let's consider the WebMethod that returns a Hashtable through a DictionarySerializer wrapper as shown in the following code:

Code:

[WebMethod]
public DictionarySerializer GetHashTable()
{
    Hashtable ht = new Hashtable();
    ht.Add(1, "Aaron");
    ht.Add(2, "Monica");
    ht.Add(3, "Michelle");
    return new DictionarySerializer (h1);
}

S.Vinothkumar · #34 (**permalink**) 09-06-2007, 01:41 AM

The XmlSerializer errors when serializing an object with a public property of type IList<T>. Since IList<T> is an ICollection, this should work.

Also, it similarly errors when using properties that are of any interface type that inherits from IList<T>. Making that interface explicitly implement IEnumerable doesn't work either (even though the documentation implies that this should work).

XmlSerializer does not support members of type ICollection or IEnumerable since V1. It requires that all members typed to collection types have a default indexer and Add method. ICollection and IEnumerable both do not have Add methods.

In the following msdn link explains about this error.....

Feedback: XmlSerializer can't serialize properties of type IList<T>

Hi friendz,

I have web service written on C#
I want call this service from code on C/C++ (I want that this code stably working)

What is better way to do this call? What framework better use? Axis C++ 1.x or Axis2C ???

amansundar · #36 (**permalink**) 09-06-2007, 07:19 AM

Well I cannot comment on the suitability of Axis2 C++, because I did not use it for some time. And I could not test it with C#.

But on Axis2/C, you can interop with .NET. Also, if you want WS-* stuff, such as WS-Addressing, WS-Security and WS-RM, then you would be better off using Axis2/C as it has proved to work with .NET with those specs.

Hello,

I have created a web service and am trying to use it in a Windows application. But I'm getting the error when I run my code as follows,

The request failed with HTTP status 401: Unauthorized.

I've created a virtual directory in IIS and am trying to run it locally.

Any thoughts would be great.

Here is my code:

private void button1_Click(object sender, EventArgs e)
{

myService.Service service=new myService.Service();
MessageBox.Show(service.Message());
}

amansundar · #38 (**permalink**) 09-07-2007, 05:39 AM

Have you set the virtual directory so that allows anonymous authentication?

You should Allow access for the IIS anonymous user.

S.Vinothkumar · #39 (**permalink**) 09-07-2007, 06:31 AM

Hi friend,

If Anonymous is allowed then you need to check permissions on your application folder. Give Network services and ASP.NET user permisison. And if your Web Service uses other resources like writing to file etc you need to check permission to those resources.

krishnakumar · #40 (**permalink**) 09-07-2007, 08:09 AM

This might seem like a silly questions.

We are moving web service from out test service to production.Now my Web Application is referencing Web Service on the test server. When i move my application to production, i would like to reference the production server instead. Would it be possible to change the reference link by changing the link to the web service through web.config?
